Keywords: pHEMT; Double Recess; Gate Formation; Field Plates; Plasma Damage; Dry Etch
A pHEMT gate formation process using a dielectrically defined gate window with no plasma damage to the gate layer has been developed. The process is compatible with field plates of arbitrarily large dimensions and is extendable to a reduced gate length through the use of a dielectric spacer process.
